一类离散Hill方程的Hyers-Ulam稳定性

Hyers-Ulam Stability For A Type Of Discrete Hill Equation

Douglas R. Anderson, Masakazu Onitsuka

摘要:

建立了一类二阶周期系数线性Hill型$h$ -差分方程的Hyers-Ulam稳定性.利用一阶周期系数的$h$ -差分方程的结果,我们还建立了一个Hyers-Ulam稳定常数.提供了几个有趣的例子。作为一个有力的应用,我们利用主要结果证明了一类三阶周期系数的$h$ -差分方程的Hyers-Ulam稳定性.

英文摘要:

We establish the Hyers-Ulam stability of a second-order linear Hill-type $h$-difference equation with a periodic coefficient. Using results from first-order $h$-difference equations with periodic coefficient of arbitrary order, both homogeneous and non-homogeneous, we also establish a Hyers-Ulam stability constant. Several interesting examples are provided. As a powerful application, we use the main result to prove the Hyers-Ulam stability of a certain third-order $h$-difference equation with periodic coefficients of one form.
